Also, are the house next to you in poor condition? 

It would be prudent to get inside if at all possible but I understand in such instances its probably not possible.The one we bought recently was listed on the MLS and we were able to see at least some pictures of the inside so we knew a little bit about the condition.

Some other good ones: Set for Life by @Scott Trench, 10X Rule by Grant Cardone, and Cashflow Quadrant.

I have bought, held and sold over 20 SFH and duplex units in my previous real estate "life" as it were.I realize that analysis paralysis can be very real, even more so for someone like myself that needs to see numbers that I find attractive and reasonable. 

One of the conditions is: "Pre-Auction Offers - Offers must be submitted at least 48 hours prior to the start of the Auction Event.

We have a listing coming up in that area, asking for $599k (average condition, no major repairing needed) and it is priced to sell quickly. 

@Nadine Delille It's definitely not easy, but nothing good in life comes easy.

Is 20-30% enough to budget for repairs and vacancy, if the buildings are in great condition?

So, I set off on a quest to learn about business and that's when I discovered a book that has forever changed my life since then - The Personal MBA by Josh Kaufman.

You now divide the number of properties available by the number under management and you have the actual vacancy and occupancy rates.Real life example:Today, I opened an email from a local Turnkey company advertising for more rental agents.
